On kernel 2.4.8-r4, I can boot off a SATA drive and mount an IDE drive and see my CD-ROM and DVD drive. On kernel 2.4.8-r9, I can boot off SATA and see my CD-ROM and DVD drive as long as I don't have the IDE hard drive installed. Once I install the IDE hard drive, the CDROM, IDE harddrive, and DVD drive do not get their /dev/* files created during boot. I'm using a MSI K8N Neo2 motherboard with nVIDIA nFORCE3 chipset. Reproducible: Always Steps to Reproduce: 1. Boot 2.4.8-r9 off a SATA drive with no IDE hard drives and see everything looks fine. 2. Add an IDE hard drives and boot. Notice no device file in /dev/* for IDE drives Actual Results: Hardware not visible Expected Results: devfs should have create /dev/hda1, /dev/cdroms/cdrom0, etc Portage 2.0.50-r11 (default-amd64-2004.2, gcc-3.3.4, glibc-2.3.4.20040808-r1, 2.6.8-gentoo-r4) ================================================================= System uname: 2.6.8-gentoo-r4 x86_64 AMD Athlon(tm) 64 Processor 3500+ Gentoo Base System version 1.4.16 Autoconf: sys-devel/autoconf-2.59-r5 Automake: sys-devel/automake-1.8.5-r1 ACCEPT_KEYWORDS="amd64" AUTOCLEAN="yes" CFLAGS="-pipe -O2" CHOST="x86_64-pc-linux-gnu" COMPILER="" CONFIG_PROTECT="/etc /usr/X11R6/lib/X11/xkb /usr/kde/2/share/config /usr/kde/3.3/env /usr/kde/3.3/share/config /usr/kde/3.3/shutdown /usr/kde/3/share/config /usr/lib/mozilla/defaults/pref /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-pipe -O2" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs ccache" GENTOO_MIRRORS="http://ftp-mirror.internap.com/pub/gentoo/ http://gentoo.binarycompass.org http://gentoo.ccccom.com http://gentoo.eliteitminds.com" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X amd64 apache2 apm arts avi berkdb bitmap-fonts cdr crypt cups curl dvd dvdr encode esd ethereal f77 foomaticdb gdbm gif gnome gpm gtk gtk2 imlib jpeg libg++ libwww mikmod motif mozilla mpeg ncurses nls nogcj oggvorbis opengl oss pam pdflib perl png python quicktime readline sdl slang spell ssl tcpd truetype xml2 xmms xprint xv zlib"
Please upload dmesg output from both kernels as attachments
Created attachment 41864 [details] 2.6.8-r4 boot up - OK
Created attachment 41865 [details] 2.6.8-r9 boot up - missing IDE drives
Thanks - could you now please upload the .config files for both?
Created attachment 41891 [details] config boots okay
Created attachment 41892 [details] config when no IDE in /dev
Comment on attachment 41892 [details] config when no IDE in /dev Thats not a config, thats a kernel binary!
Created attachment 41893 [details] config when no IDE in /dev whoa! back off the coffee.... no wonder it took a while to upload
Tried kernel.org's 2.6.9-bk4 and this problem does not occur in that code base. Added benefit of 2.6.9 is it sees the motherboard's Realtek ALC850 sound chip which isn't in the 2.6.8 codebase. The gentoo-dev-sources-2.6.9 doesn't compile on AMD64. Looks Daniel posted gentoo-dev-sources-2.6.9-r1 a few hours ago. I'll try that soon.
Works with 2.6.9-gentoo-r1
